According to the invention the position of loading/unloading stations SC/SD as rega-rds the transEer means 1 may be alternated for having one loading station SC into centre and two unloading stations SD into extremities of the transfer means 1 for permitting to transfer the articles from one fast machine to two slow machines.
It is also possible to utilize one loading station SC
only and one unloading station SD only with several intermediate dwell stations SI for permitting to transfer the articles from a first fast machine to a second fast machine.
According to a further embodiment, a machine for the automatic transfer of pantyhose and similar tubular articles according to said method in conformity with the invention and with reference to Figures 9 to 11 of the attached drawings and provided for transferring the pantyhose articles from two machines of a first type to a machine of a second type, is essentially made up of:

According to the invention the position of loading/unloading stations SC/SD as rega-rds the transEer means 1 may be alternated for having one loading station SC into centre and two unloading stations SD into extremities of the transfer means 1 for permitting to transfer the articles from one fast machine to two slow machines.
It is also possible to utilize one loading station SC
only and one unloading station SD only with several intermediate dwell stations SI for permitting to transfer the articles from a first fast machine to a second fast machine.
According to a further embodiment, a machine for the automatic transfer of pantyhose and similar tubular articles according to said method in conformity with the invention and with reference to Figures 9 to 11 of the attached drawings and provided for transferring the pantyhose articles from two machines of a first type to a machine of a second type, is essentially made up of:
